What these numbers mean (and don't)
- Single-family homes. These are single-family home figures for all of Ada County. They're county numbers, not figures for any one city or ZIP code.
- Days on market. Counted in days from the listing date to the date the home goes pending.
- Median price. Half the homes sold for more and half for less. It describes the whole county's sales that month, not any one home.
A county median can't price your home. Size, condition, updates and the street all matter. For a range on your home, request a home value or read What is my Idaho home worth?. To read prices, status and days on market on a single listing, see How to read the Idaho housing market on BrowseIdaho.
